The Belle II experiment at the asymmetric e+e- SuperKEKB collider is a major upgrade of the Belle experiment, which ran at the KEKB collider at the KEK laboratory in Japan. The design luminosity of SuperKEKB is 40 times higher than that of KEKB, and the planned integrated luminosity is 50 times higher than that of Belle. Such a large data set allows for a broad physics program studying heavy B and D meson decays, and heavy lepton decays. Belle II will measure leptonic and semileptonic decays, radiative decays, inclusive decays, rare decays, CP-violating decays, and also search for forbidden decay channels. The good hermeticity of the detector and high acceptance facilitate measuring a wide range of observables. The sensitivity of the experiment to new physics should be much greater than that of the "B factory" experiments Belle and Babar. In this talk we present the expected physics performance and current status of Belle II.
